Abstract: ABSTRACT OF THE DISCLOSURE    A sailing craft having a hull with a longitudinal midplane.   A primary boom is pivotally mounted on the hull for 360° continuous rotation in either direction about a central vertical axis.  The primary boom is connected by lines to a sail boom.  At least one angled mast is mounted to the hull and extends upwardly.  The mast has a top, the top is disposed approximately above the central vertical axis of the primary boom.  A sail is carried by the sail boom and extends upwardly and substantially symmetrically about the central vertical axis.  The sail is supported from the top of the at least one mast.  The sail boom with the sail thereon has completely free 360° rotation in either direction avoiding contact with the mast.  The sail has flake lines swivelably connected to the top of the mast permitting rotation of the sail and flaking of the sail.  A tension device maintains tension on the top of the halyard so the sail luff becomes tight when the primary boom rotates either end forward.

Title: Process for producing lower alkyl fatty acid esters
Inventor: BOOCOCK DAVID G B
IPC: C07C67/02
Filed: 1994-09-08
Abstract: The present invention provides improved processes for methanolysis and ethanolysis of fatty acid glycerides such as those found in naturally occurring fats and oils derived from plants and animals.   The processes comprise solubilizing an oil or fat in methanol or ethanol by the addition  of  a  cosolvent  in  order  to  form  a  one  phase reaction mixture,  and adding an esterification  catalyst. The  processes  proceed  quickly,  usually  in  less  than  20 minutes, at ambient temperatures, atmospheric pressure, and without agitation.  The cosolvent increases the rate of the reaction by making the oil soluble in the methanol,  thus increasing contact of the reactants.  The lower alkyl fatty acid monoesters produced by the processes can be used as biofuels and are suitable as diesel fuel replacements or additives.

Title: Blind rivet
Inventor: BROWNE LAURENCE ANTHONY
IPC: F16B19/10
Filed: 1995-04-12
Abstract: A self-plugging blind rivet (10) comprises a tubular rivet shell (11) and a stem (15) disposed in the bore (14) of the shell (11). The shell (11) comprises a generally cylindrical shank (12) with a preformed head (13) at one end. The stem (15) projects from the head end of the shell (11), and has a head (19) which abuts the tail end face (21). The shank (12) has two axially spaced zones (25, 29) of reduced diameters formed by rolling or crimping, and an intermediate zone (26, 27, 28) between them. The projecting stem is pulled to compress and deform the shank (12) to form a blind head.      In order to avoid cracking of the blind head and to improve the grip range of the rivet, the intermediate zone has two transition zones (26, 28) forming an angle of 2° to 20° with the axis of the shank (12) in which the diameter of the shank increases progressively from that of the zones (25, 29) to a maximum in the intermediate zone (26, 27, 28).
Patent CA-2149481-A1 (CA)
Inventor: GIESE LUDI
IPC: B62D33/07
Filed: 1995-05-16
Abstract: The invention relates to an apparatus which automatically locks the hood of a vehicle in a position which allows access to the engine. The invention includes a swing arm which is spring loaded and pivotally connected to the support structure of the vehicle, like the vehicle frame, near the hood hinge and away from the engine. When the hood is opened and the hood hinge pivots, the swing arm automatically follows the hood hinge until the swing arm reaches a position which prevents the hood hinge from pivoting in a direction which would result in the hood closing. In this way the invention automatically locks the hood to prevent premature hood closure which could injure the driver or maintenance personnel.

Title: Direction finder
Inventor: BAUMHAUER JOHN CHARLES JR
IPC: H04R3/00
Filed: 1995-05-18
Abstract: A direction finder arrangement advantageously employs a plurality of transducers to derive a plurality of predetermined polar directivity patterns each of which has a predetermined spatial orientation pointing in a predetermined fixed direction relative to each of the other polar directivity patterns. The polar directivity patterns detect a plurality of amplitude values of a propagating wave approaching at different angles relative to the plurality of spatially oriented polar directivity patterns. Then, the detected wave amplitude values are processed to determine an estimate of a direction toward the source of the arriving wave. More specifically, the detected amplitude values are processed to obtain an estimate of the directional orientation of a hypothetical polar directivity pattern pointing toward the source of the arriving wave.

Patent CA-2151540-A1 (CA)
Inventor: KOBAYASHI WILLIAM THORU
IPC: F23D11/38
Filed: 1995-06-12
Abstract: A combustion method is provided for carrying out combustion with reduced generation of nitrogen oxides. The combustion method involves partially combusting a fluid fuel stream with a low velocity oxidant and thereafter mixing and combusting the resulting product with a secondary oxidant stream diluted with ambient gas.  The velocity of the secondary oxidant stream is either increased to reduce the nitrogen oxides emission level or adjusted to provide the desired secondary oxidant/low velocity oxidant ratio which is useful for further decreasing the formation of nitrogen oxides. Normally, increasing the ratio and/or velocity further decreases the nitrogen oxides emission level.  When liquid fuel is employed, it is atomized with atomizing fluid in such a manner to produce a liquid fuel stream having a very narrow spray angle.  The production of such a stream allows the burner to be operated without water cooling.  Moreover, such a stream, when combined with the above combustion method, unexpectedly provides effective and efficient combustion with reduced generation of nitrogen oxides.
